Zoho Add-In for Firefox

There used to be a clipper type add-in for Firefox that clipped bits of webpages, as needed, and added them to Zoho Notebook. I can't seem to find it any more.

The Zoho add-in I could find allows local files to be uploaded to Zoho, but I can't figure out any real use for it. It doesn't seem to replace the clipper add-in that was previously available.

Is there such a clipper add-in available anymore?
